When you're in the FITS viewer and use a mouse scroll wheel to zoom-in, if you're not careful and scroll it too much, which is easy to do with Apple's POS scroll mouse it will ultimately lead to a crash. It zooms too far and appears to causes a memory leak as I've seen memory usage spike.

I've accidentally flicked the mouse on that screen, it would zoom way in or out then Kstars became unresponsive at first followed by a crash some time later. The solution is to not use that mouse and it works fine with another one. The mouse seems overly sensitive and possibly the software needs to ensure it doesn't accept input past a certain point.

I hope that helps.

It's very stable IMO but I do know how to crash Kstars/Ekos. Get the 8GB for the slight extra cost.

My WiFi hotspot is always running along with ethernet cable connection. It's also running in the 2.4ghz band and I've never had an issue with USB3 on RPi4.

The only exception is when using 16bit drivers with the ZWO ASI120mm mini guide camera. Not sure if it defaults to 8bit of not in newer builds but it always caused Kstars freezes and crashes during plate solving.

I've imaged many many hours, no problem with 2.4ghz Hotspot and RPi4.

While I generally used wired ethernet, I've not had a problem with the HotSpot connectivity using a USB3 ASI5433MC camera.

RPI's wire-connected to my router (through a hub). I assigned a fixed IP for SM - like 192.168.0.121.
All network settings - default.
I never had issues with the wired connection.
I did have issues with WiFi (RPI4. RPI3 was fine) but now it's also good (as of 1.5.0. Again, everything is default).
In the field I use a 10" HDMI monitor and USB mouse/keyboard. No network. <-- really like this setup.

I am going back to this as it is so much easier to focus without the delay inherit in using wifi or the iOS app. I've been hesitant about it as some ground loop condition blew out the HDMI port in my RPi3 when the battery ran out and i plugged in the 12vdc connector to the monitor and it sparked, no more video :( I will just me more careful about applying external power to the monitor while and ensure my batteries are charged.

I've used my USB 3 ASI533MC camera and a USB3 hub without any issues on RPi4. I've connected the USB 2 devices directly to the RPi4, to the ASI camera ports and to the hub. I've disconnected them completely and plugged them back in, never a problem except for the AVX cable connecting to a USB / Serial Prolithic adapter, unplugging it requires a reboot to get it going again.

Correct, you use the SD card only to start up the Pi4, and point to the SSD, but the entire system files are on the SSD, so any system file swapping and file downloads now goes through USB3 and the SSD, not through the SD card bottleneck. MUCH faster, plus you can now also use a swap file on the SSD. I need that on occasion when using FITS viewer at high magnification during the run to inspect the quality of my guiding. That can max out your memory and crash the machine otherwise.

This explains my crashes as I have been doing the same thing, inspecting the subs by zooming in and often it would stall for up to one minute and recover or Kstars simply crashes.

My D7500 DSLR had higher resolution than the 533MC does, 22MP vs. 9MP and it routinely gave 15fps or higher, even on the RPi3. Makes focusing difficult a 2FPS, especially with the amount of lag. I don't think 2FPS is normal for a USB3 device and the 120mm is USB2. I am using the USB2 hub built-in to the 533 and maybe those connections are slowing the rest of it down. I think I will put the mount direct to USB2 on the RPi4.

El Corazon - What kind of frame rates to you get with RPi4 and a ZWO USB 3 camera in video mode, in the CCD Section?

The new ASI533MC fails to get even 2 FPS. and downloading an image takes just under 3 seconds. Something is amiss as it is much slower than the ASI120mm mini where I can get 20FPS

El Corazon - see if any of your devices have 8bit / 16bit drivers and try the 8bit settings. I had to do this with the ASI120mm mini, not sure if that is the same as your 120mm-S.

Sounds similar to the problem I was having with my ASI120mm-mini guide camera. Everything worked fine indoors, would run for hours but when I plate-solved it wall came tumbling down.

The solution was to change the camera for 16bit to 8bit in the INDI control panel. Once that was done, it worked as expected.
